SNAP FASTENER.

hpplieation filed June 9, 1923. Serial No. 644,414.

To all whom it may concern:

Be it known that I, GEORGE HENRY EL- WELL, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Snap Fasteners, of which the following is a specification.

My invention relates to improvements in snap fasteners.

The object of my invention is to provide a snap fastener the stud and socket members of which are adapted for selectively fixed relative positions.

With this and other objects in View, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts hereinafter described, illustrated in the so companying drawing and particularly pointed out wherein patentable novelty is claimed for certain features of the device, it being understood that within the scope of what hereinafter thus is claimed various changes in form, proportion, size and other minor details of. the construction can be made without departing from the spirit or modifying any of the advantages of the invention.

The following is the description of an embodiment of my invention reference being had to the accompanying drawing in which Figure 1 is a side view of mounted members in readiness for connected engagement; Figure 2 is a top view of stud'memher and mounting; Figure 3 is a cross-sectional view of the next preceding figure on line bb of that figure; and Figure 4 is a cross-sectional View of connected members on line a-a of Figure 1..

Referring more particularly to the drawing in which similar numbers refer to similar parts, socket member 1 and stud member 2 may be of any of the various types of snap fasteners in so far as the means of connecting the members in fastened position is concerned. The novelty which my invention introduces is a means by which one or both of said fastener members may be slidably mounted and adapted to varying fixed positions within the S00 e of provision made therefor. In the v rawing I preferabl show only the stud as the slidmg mem er mounted on base-plate 3 and slidingly held on said plate by turned over edges 4, as shown in Figures 1 and 2. The main portion of stud 2 is preferably a onepiece construction struck up from sheet metal and providing a hollow interior 5 within said stud, as shown in and 4:. The head'6 of said stud is perforated to provide opening 7 in the top of said head, said opening communicating with said hollow interior. The base 8 of said stud is a separate piece held in place as shown in Figures 3 and 4. Base-plate 3,

as shown in Figure 2, is provided with a 861188 of perforatlons 13 each perforatlon being adapted to receive 1n sequence the rounded extremity 12 of pin 11. The socket member 1 and the stud member 2, the latter provided with my push-button element 10 as aforesaid, are so constructed to co-operate that when the socket member 1 is snapped onto the stud member 2 the inner portion of said socket member construction operatively engages the push-button element 10 through opening 7 in the top of the stud head 6 and, when the extremity 12 ofpin 11 substantially registers with one of the series' of perforations 13 in base-plate 3,

said push-button element 10 forces said extremity 12 into said perforation and thereby locks the stud member in a fixed position with regard to base-plate, as shown in Figure 4. In operation it may be preferable to slide the stud member to the desired position and manually press the pushbutto-n element until extremity 12 enters one of said series of perforations 13 and then snap the socket member onto the stud member.

Disconnected from the socket member the stud member is readily made to slide on base-plate 3 without manually operating the push-button element; for the rounded extremity 12 of the metal immedlately bounding said perforations 13 provides a cam surface adapted to automatically lift the push-button element as the stud member is manually forced along base-plate 3.. With the stud member 110 Figures 3 6O push-button element 10 op- 70 in 11 co-operating with in fixed position as regards base-plate 3 the connecting and disconnecting of the fastener members are effected in the manner usual to snap fasteners.

It may be advantageous, in the construc tion of base-plate 3', to substitute a series of indentations for perforations 13. 'With such substitution, however, extremity 12 of pin 11 need not be rounded provided that such indentations are constructed to pro vide'a cam surface adapted to guide the pin extremity in its travel along' base-- plate 3.

What I claim-is: j i

1. A snap fastener comprising stud and socket members having. an 'interlocking means; a base-plate upon which one of said members is slidingly mounted, said base-' 'plate having an attaching means and also maintain said sliding member in a fixe having a series of indentations, and said sliding member having a hollow 1nter1or and openings communicating with said interior and certain of said openings adapted to register in sequence with said indentations as said sliding member travels said base-plate; and means 0 erable within said hollow interior and a apted to project through said openings to co-operate with said socket member and said indentations-to rigidly sltlon' as regards said base-plate.

2. A snap fastener comprlsing studand socket members having an' interlocklng meansya" base-plate upon which one of saidmembers 1s slidingly mounted, said base:

plate having 'an attaching means and also having a series of indentations, and said sliding member having a hollow interior and openings oppositely located and communicating with said interior at its base and interlocking extremity; a shifting filler element with which the interior of said slide ing element is provided, said shifting element being adapted for alternate projection through said oppositely located openings and being also adapted for, entrance into said indentations in sequence as said sliding member is made to travel said baselate, the ,Oth fastener member in inter ocked engagement with said sliding mem ber fixedly engaging said shifting elementand maintaining said shifting element in a projected position whereby sald shifting element is rigidly held in one of said indentations and, said slidin member is thereby maintained in a fixe said base-plate.

3. An adjustable stud member of a stud and socket fastening device, said stud com position as regards prisingva hollow stud member having openings oppositely located in its head and base and communicating with said hollow interior; a push-button element with which said interior is provided, said pushbutton element being manually operatively accessible through the opening in the head of said stud to project a pin,

with which said push-button element is provided, through" said opening in the base of said stud; a base-plate upon which said stud is slidingly mounted, said base-plate beingprovided with an attaching means and also'with-a series of indentationswith which the opening in the base of said stud is adapted to register in sequence asjsaid stud travels said base-plate; and means with which said push-button element is provided, said means being adapted to co-operate with a socket member in interlocked position with said stud member to rigidly maintain said pin projectedthrough the base'of said stud and into one of said indentations.

4. A'snap fastener comprising stud and I socket members having an interlocking means: a base-plate upon which one of said members is shdably mounted, sa d baseplate having an attaching means and also having a series of perforations, and said sliding member having a hollowinterior and openings communicating with said interior and certain of saidopenings ada ted to register in sequence with said per orations as said sliding. member travels said base-plate; a movable pin with which said sliding member is provided, said pin having arounded extremityand being adapted to project through said registering opening and rest in any of said perforations;'and means operable within SilldllOllOW interior and adapted to co-operate with said socket member .and said pin to rigidly maintain said slidlng member 1n a fixed posltion as regards sald base-plate.

5. A sliding stud member ofa stud and.

substance.
